That was much easier than I expected it to be, and I'd be damned if it wasn't for the creep. I noticed it disappears if I place too much of it, so I wasted some of it just in case. It may have something to do with entity limit.

Here's the overall strategy:
Normal bare minimum amount of shield, sometimes used for damage
Corn some fly damage, protected by the stone poop
Red damage and used to ignite toxic clouds
Poison most effective against flies and sometimes used for bigger explosions
Black worse version of poison, quite useless actually
White takes time and effort to be most effective, has to be connected to creep and at least one stone poop
Stone used for solid protection and keeping the creep effects
Bomb pretty much same as red poop, but more useful
Fart knockback and poison at a very close range, usually used for clouds
Diarrhea duite annoying way to deal some damage
Brown creep main source of damage, hush has to stay at it at all times, sometimes used to deal lots of damage with white poop
